Here's the full list of changes for the 1.4.04 beta:

Public Betas can be downloaded from here. If you have any issues while using a beta, you can just install whatever version you were using before, or grab the current released version from the Trial/Download page. The standard licensing rules apply - you'll need to have a current license key to run these (or be in an active trial period). If you encounter a bug in a public beta, please let us know by sending an email to with as much information as you can recall about what you were doing so we can try to reproduce it and fix it.

We'll gather feedback from those users to try to fix any issues we missed before doing a general release. We'll test to the point we normally would before a release, then make the new version available here for anyone who wants to try it. In order to try to improve our testing, we're going to start doing a 'Public Beta' period for new releases.
